It's the end of the year. Yokoyama, Tamaki and Takeuchi all have plans to transfer schools. Saddened, Yoshino decided to hold 'Asuko March' (a school tradition) to make a final memory with them altogether. This causes her to fall out with the whole class. After finding out everything Yoshino has done to help Yokoyama and Tamaki, the class decide to help her complete Asuko March.
